Hepatic steatosis, visceral fat thickness and subcutaneous fat thickness were also assessed at ultrasonography.RESULTS: Higher c-IMT values were found in the presence of NAFLD (90 patients), even after adjustment for indices of general and abdominal obesity and for the principal cardiovascular risk factors (0.84±0.10 mm vs 0.71±0.10 mm, P<0.001). The prevalence of carotid plaques was 57.8% in the patients with NAFLD vs 37.5% in the patients without this condition (P=0.02). The adjusted relative risk of having carotid plaques for patients with NAFLD was 1.85 (95% CI:1.33-2.57, P<0.001).CONCLUSION: An incidental finding of hepatic steatosis may suggest the presence of silent carotid atherosclerotic lesions.展开更多
